Involved vehicles are marked “open” on the Investigate Vehicle History screen in GM Global Warranty Management system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.

Condition

On certain 2016-2017 model year Chevrolet Cruze vehicles, the center high mount stop lamp (CHMSL) fasteners may back off over time and cause a water leak, allowing water to flow into the rear compartment battery tub. When the battery tub fills with water to a height of 50mm or more, the DC/DC converter module board and connector are exposed to water which may cause corrosion. If water drains below the DC/DC converter, a resistive short may occur on the printed circuit board which could result in an unattended fire when the DC/DC converter is powered.

Correction

Dealers are to inspect for water damage in the battery tub electrical components, and replace the CHSML gaskets and nuts (adding Loctite to the nut).

Parts Information

Important: Due to limited initial parts availability, dealers are encouraged not to order recall parts for use as shelf stock.

Reminder: Parts may be removed from Retail Inventory Management (RIM) management. Dealers should review the affected parts to confirm RIM managed status. Parts may have quantity limiters in effect.

Dealer Responsibility

All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers’ possession and subject to this program must be held and inspected/repaired per the service procedure of this bulletin before customers take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration, or any other purpose.

All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified for sale within the CPOIS system, or once again be used in the CTP program.

Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle, or ownership, through January 31, 2019. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the involved vehicle listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. A copy of the customer letter is provided in this bulletin for your use in contacting customers. Program follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in your facility for service through January 31, 2019, you must take the steps necessary to be sure the program correction has been made before selling or releasing the vehicle.
